Start Assist Control Strategy of Integrated Electronic Parking Brake System

Abstract:

n order to reduce the technical requirements of car start to the driver and avoid the wrong operation that will shorten the life of parking brake system, an integrated electronic parking brake system, which has motor and transmission mechanism, was proposed. The driver can realize the vehicle parking through the button of parking brake system operation. The start working conditions of vehicle were analyzed and concluded in detail. At the same time, the resistance of vehicle start was calculated, which provides basis for the research of control strategy. The research on structure and working characteristics of integrated electronic parking brake was carried out and the feasibility of start assist control was analyzed. The real vehicle test verified the correctness of start control strategy of integrated electronic parking brake system, realized the assistant control of vehicle start, reduced the dependence of drivers technology to vehicle start and increased the life of parking brake system.
